Notes: 

Clinical Indications: The measurement of serum precipitins by gel diffusion is a commonly used technique to assess exposure and sensitization to various antigens. Serum precipitins are antibodies that form visible lines with their corresponding antigen when they diffuse toward each other in agarose gel. They are usually of the IgG or IgM class. In general the detection of antibodies by gel diffusion will be less sensitive than enzyme immunoassays (ELISA methods). The interpretation of a positive gel diffusion test (i.e. the presence of serum precipitins) must be made by the physician in context of the patientís history and clinical findings.
